VFD for High Ambient Temperature | VLT Lift Drive - Danfoss India

Reliable operation and excellent ride comfort

The VLT® Lift Drive is designed to provide reliable operation and excellent ride comfort for a minimum of 2.1 million cycles when running at an ambient temperature of below 45°C. Ideal for new projects or for retrofits, it operates without motor contractors and can be quickly and easily commissioned in less than 10 minutes.

Designed for all motors, including asynchronous, induction, permanent magnet, copper rotor and direct online PM motors, the VLT Lift Drive is suitable for both traction and hydraulic lifts in open- or closed-loop systems.

The compact design and intelligent cooling concept means it easily fits even into small installation spaces. And a range of built-in features eliminates the need for extra components. Scalable RFI filters minimize electromagnetic interference, integrated DC chokes suppress harmonics while ensuring the drives meet relevant EMC standards, and step-up, step-down transformers are not required.

Supply voltages and power range

380-400 V...4-55 kW

Features and benefits

Travel comfort is enhanced thanks to a range of noise-reducing features

Energy savings can be achieved as cooling fans run only when absolutely necessary

The drive is quick and easy to commission as it fits all common feedback systems and there are just 10 parameters to set

The drive operates reliably in harsh conditions due to specially coated circuit boards

Components remain firmly in place in environments with high degrees of vibration thanks to the ‘ruggedized’ version

Applications

Mid-range to high-rise residential and commercial building lifts, industrial site freight lifts, mine-shaft lifts, ‘recreational’ applications, such as ski lifts, boat lifts, aircraft lifts or elevators, vehicle lifts, walkways.

VLT®Advanced Active Filter AAF 006

The flexible filter for central/decentral harmonic mitigation

The VLT®Advanced Active Filter AAF 006 improves system efficiency and increases grid robustness to avoid downtime. It can compensate for individual drives or it can be installed as a compact standalone solution at a point of common coupling to compensate for several loads simultaneously.

The active filter ensures optimal harmonic suppression independent of the number of loads and their individual load profile. In addition, it corrects the power factor and balances the phase load to provide optimal energy utilization.

Supply voltages and power range

380-480 V...190-400 A

Features and benefits

The lifetime of electronics are prolonged thanks to innovative concepts such as back-channel cooling

Durability and reliable operation is improved thanks to coated PCBs

A high degree of customization is possible due to the wide range of options

Running costs are low as a result of features such as sleep mode, progressive switching frequency and power factor correction

Servicing is easy due to the modular design

Applications

A range of applications for the water and wastewater, marine, oil and gas and mining industries.
